Is 3D supposed to be limited? - HTC EVO 3D

So is anyone else seeing double image if they dont film their subject in a sweet spot? Seems kind of pointless doesnt it? If I am filming stuff, I would prefer to not tell my subject that they cannot move beyond a certain zone.
Or... is my 3d defective?

I only see issues if I am close to something, like a macro shot

Ive had the same problem. Taking 3D pictures of moving objects just doesn't work well.

Without a quick enough shutter speed, taking pictures of moving objects period doesn't work well.

my problem isnt just moving objects. it is anything that is NOT in a certain zone. If the object being filmed is too close or too distant, it doubles (instead of 3d).

With 3d photography, there ARE limitations on distance.
Remember, a camera doesn't work like your eyes which are able to do more than just focus.
A camera lens is FIXED in a specific position and when you change your focal points the fixed position may be either to wide or, when focusing at distance, too narrow.
Movie makers and professional photographers are aware of this and can work around it. Specialized 3d photography actually uses 2 cameras in sync with a rail that separates the cameras based on the focal point.
Here's a simplified example of the rail for home use:

For what the evo and point and shoot 3d cameras do, it's just fine as long as you know the limitations of distance (both macro and >40ft or so)

I appreciate this info... but... my evo 3d is struggling with objects even > 8 feet.

is anyone else experiencing the same issue? should i take it back?

To get as close as possible to a perfect 3D experience for human eyes, a 3D camera needs its two lenses to be the same distance apart as our eyes are. Notice the 3VO's "eyes" are only 1.375" apart. My eyes are closer to 3" apart center to center. What it means is that the near and far extents of the view taken will either be hard to align for focus or impossible and thus ignored by one of our eyes or the other. Far elements won't have as much 3D impact anyway, except in contrast to near elements in the same scene. You'll notice broad distant landscape scenes aren't the choice shots as 3D samples. Pick scenes with foreground (not too close) and background (and even middle ground) elements to shoot, and your shots will turn out fine. Make sure your camera is level though. If you don't then you won't see the 3D effect until you re-create that tilted relationship between your eyes and the viewscreen.

[Q] Actual visable resolution

Sorry if this has already been asked but anyone know if the phone has 960x540 resolution after the parallax barrier? I'm not sure if the 960x540 is the actual screen resolution and with the parallax barrier it would half either the vertical or horizontal. So viewable screen res (since u cant exactly turn off the parallax barrier) would be either 480x540 or 960x275 per eye?
This could be a potential problem for web page viewing if the page can only be displayed at 480x540 or 960x275 depending on how they align the barrier.
I remember reading that the 3D is software controlled, so the parallax barrier (which is like a fine lcd gauze) can be switched on and off in software.
So in 3D on mode the resolution will be 480X540, and off will be the full 960x540.
I am willing to be corrected on this by somebody more knowledgable!
From my understanding the parallax barrier is a static physical filter.
Based on my experience with the 3ds, which also uses a parallax barrier at 800×240 effectively 400×240 per eye, when you turn off the 3d effect it is still displaying 2 images but both images are from the same view point. The parallax barrier is still working but since both eyes are seeing the same 400x240 image you do not get the 3d effect nor the full resolution of the screen.
Im just curious if out of 3d mode (for example 2d web browsing) the phone will be able to use the full 960x540 resolution while sending 2 480x540 images, one to each eye.
that does it, I'm officially confused about it now.
My assumption knowing nothing about the technology behind it is the resolution they quote is the effective resolution in 2d, if it was half that a lot of ppl would b pissed

I'm just taking a guess here but it's probably qHD total with each eye seeing half of the pixels. From what I've seen with the cross eyed 3d pictures your mind will automatically put them together so it should looks like a normal qHD screen.

I posed this same question over at Android Central a few days ago and was informed (presumably correctly) that the parallax barrier was dynamic, meaning 2D resolution was full qHD.
That's interesting, i thought about alternating the pixels (odd pixels to 1 eye and even to the other) but when i tired it with some text on the 3ds it looked like garbage. I didn't even think about alternating the frames.
oh well looks like we will just have to wait and see. I wonder how the 3d phones that are out now get around the parallax barrier in 2d
I think the evo 3D will most likely employ the kind of parallax barrier that can be turned off, meaning 2D will be completely normal qHD. If not, surely some of the people who've had hands on experience with it would have noticed it and mentioned it by now.
I was originally concerned about the halving of the horizontal pixels for 3D content, but since each eye sees different images, it's hard to really call it half resolution. Once your brain blends the two images together, hopefully it will be hard to notice any loss in horizontal resolution. Especially in dynamic content, like movies or animations.
Funny, when I look at a Nintendo 3DS, and switch off 3D, the resolution improves significantly. I'd say it goes to full 2D resolution, without combining images from different eyes. I closed my right eye and it didn't change anything. If you leave one eye closed and switch between 2D and 3D you can see the difference.

Parallax barrier stereo displays are always half res (horizontally) when the effect is on. So ScrapMaker's point that the resolution improves when switching off the 3D effect is correct. He is not saying that the resolution improves when using both eyes while the effect is on, which it does not.
The EVO 3D likely uses the same display technology as the Optimus 3D and Nintendo 3DS, where the parallax barrier is switched off in 2D mode (and therefore no loss of horizontal resolution). Basically the display is two LCD panels sandwiched together, the front panel being the normal RGB array, the back panel being a series of switchable vertical strips. When on, the parallax barrier directs the light so the each eye is limited to odd or even columns. The display is probably made by Sharp since they've owned the patents on this arrangement for some time now.
Is that parallax barrier visible at all when its turned off? Could it possibly affect sharpness/brightness/viewing angle of the screen?

It has been confirmed that the 3D effect works in both landscape and portrait, which I don't think either of those other two support. I suppose the parallax barrier could just switch orientation along with the content being displayed. But I thought the RGB array needed to be physically aligned the same direction as the parallax barrier lines. I'd love to see how they pulled that off.
peachpuff, I've had the same concerns over loss of fidelity in 2D due to the parallax barrier layer (even when off). Let's hope there is no noticeable degradation.

If it's like the 3DS, it doesn't affect the image because the parallax barrier is between the RGB panel and the backlight. Unlike the older style parallax barriers which act like a lenticular lens and were attached to the front of the LCD panel, those were permanently in 3D mode.
However, since the Sharp screens use directed light, rather than a mask, the viewing angles of the RGB elements would have to be fairly narrow in order to cull the opposite eye's frame. But I remember seeing an LCD panel with a dynamically variable viewing angle at CES a few years back, so maybe that technology comes into play here too. Otherwise the viewing angle would suffer in 2D mode. Anyhow, pure conjecture on my part, I'm looking forward to playing with the new EVO next month and hopefully a comprehensive teardown of all the new tech in there.

I used a 3ds yesterday and I have to say that I wasn't impressed. ANY slight shift in the screen cause the whole image to distort and breaking the 3d image my brain put together (if that makes any sense). And the 3D pictures looked like they were taken through a sock. I just hope the EVO 3d is better (I'm assuming it will be) because I had a headache for a good hour last night with that thing.

Granted that this garbage above was initially spewed by some poser who pretended to work for HTC/Sprint... some of the ideas are genuinely clever. I've added them to my own in the list below of what could possibly result from the dual-camera setup. Tell me what you think!
Greater detail. Using both cameras at once to capture two 5mp images and "overlaying" them is interesting. Maybe adaptively "adding" the details in one to the other? Maybe using some kind of "interlaced" trick, or maybe the tilt is a bit different so both can take pictures of 2 different [but adjacent] visual fields for "instant panorama"?
Greater depth of focus. Each camera can shoot simultaneously with a different focus, and the result easily combined into a picture with incredible depth of focus.
Sport mode (shutter speed enhancement) seems like a wonderful idea. Both cameras fire, one a few ms after the other, and the result motion compensated. The perspective difference may also be used to identify and correct for motion blur. As an instantaneous "anti-shake" this would work wonderfully, too. All in all, this would allow the camera to capture faster motion with less blur!
Double speed burst-mode. Burst mode could theoretically be twice as fast, since the other lens could fire during the recovery time of the first.
Dark mode / night owl / de-graining. A fantastic idea would be to use both cameras to capture a picture simultaneously at high ISO and use a simple perspective-corrected denoiser to drastically improve quality of night scenes, which suffer most from grain issues. Each picture is bound to have a different amount of "random noise" or "camera noise" from the two cameras, and after perspective correction (and/or motion compensation if one fires after the other), the randomness is detected and removed from the combined image.
HDR (High Dynamic Range) can be achieved with no additional delay by having both cameras snap at different exposures and combining the result, solving the "low dynamic range" problem with the Sensation and other phone cameras.
Apply all of these to video. If both capture video simultaneously, there could be some benefit in 2D mode -- timestamps of the recorded frames can allow them to be combined to produce a single video of higher effective average framerate -- again, with some simple HW perspective correction filter. It could also drastically improve the quality of night video in the same way as the above "night mode" camera use with the additional potential advantage of temporal denoising, resulting in the cleanest night video you can imagine. Not to mention the first ever high dynamic range (HDR) video on a mobile device.

It's obvious these aren't going to be included in the official ROM, but I'm sure there can be "an app for [some of] that" provided the API of both cameras are exposed. Exciting prospect, is it not? The only one of these that seems a bit hard to chew is of course the 10mp nonsense. At most the combined detail would just produce a "very nice" 5mp shot.

I don't quite get it.
Anyway, I also think it would be neat to use the two cameras to offset an alarming trend in phone cameras -- low dynamic range. Both can fire simultaneously at different exposure settings, and combined into one HDR image.
I think what they mean by the horses, is that this is kinda crap.
It's already been known that when taking 2D pictures, it uses the top-most camera only. It uses only one. Only in 3D does it use both cameras.

Yea, forget all the crap that everyone spews. Anything is possible, with the devs here on xda. As Mlin said, I'm sure there will some dev or a team of devs that will develop an app to take FULL advantage of the dual cams. Granted, I'm sure there will be plents of limits on what the cams are capable of, however, I'm sure that those limits will be pushed and that we'll eventually get max potential out of the cams.

You get an "A" for thinking so far outside the conventional box, but unfortunately I don't see any real possibility of any of that ever coming to pass, for one inescapable reason: the two cameras aren't shooting from the same location. Every concept you describe requires that both cameras see the same thing, and they don't, for the simple fact that the pictures they take are from two different physical locations.

Fixed-point location adjustment is trivial and can be performed in software/hardware with minimal effort (even perspective/angle adjustment via convolution-deconvolution of 3d signal matrix). Also, even if they weren't shooting from precisely the same location or perspective, the motion-compensated technique can be applied even to different frames in a video (making 'night shots' more doable), since the temporal element is the most tricky. If both cameras fire simultaneously, tracking synthetic "motion vectors" is utterly trivial.
Even if a developer was lazy and didn't want to implement perspective correction, a subset of the two pictures near the center (where they overlap) can be used for all of the rough work, and a simple guassian averaging function can perform the spreading (or simulated annealing) from that point.
No, location is certainly not a problem -- and even perspective is fairly easy to (accurately) account for via straightforward signal processing algorithms both in hardware and software.

[Q] Kinect has 2 cameras, Evo 3d has 2 cameras, Possibilities endless?

Ok,
so i had an idea and not being that technically minded i thought id post it as a question instead of a statement...
Why wouldn't we be able to use the 3D's dual cameras just like the Kinect uses its?
Perhaps we could port software from one to the other...
Maybe on a 3d Windows phone.. but who knows...
sent from anything but an iPhone
That's not how it works.
The cameras are used for the 3D depth, sure, but the Kinect also uses an IR sensor to shoot tiny dots of IR light, covering the room. Your movements to block this light are also recorded by the Kinect and used in translating your motion on screen.
I'm sure there will be some cool uses for a 3D camera--but it won't ever be as easy as "porting straight over" or anything like that.

He is right, the technology you are talking about just isn't fully inside the Evo 3D like it is in the Kinect sensor, although I do have a few ideas on what to do with the added 3D capabilities as a developer myself. Nice job, thinking outside the box OP.
I mean, a 2D camera can do depth and motion sensing if you calibrate it properly and SPECIFICALLY (with say, ONE object to focus on like a ball, Playstation Move I'm looking at you).
A 3D camera will offer you the depth, but calibration might offer you problems. Sure it can sense and translate depth, but I think the point of the IR in the Kinect is to take away most of the calibration and calculations necessary from there, as well as increase the accuracy of the translation.
Put another way:
If I move in front of my 2D camera, it sees me get larger and smaller--stuff like that.
If I move in front of a 3D camera, it sees me move on an axis, as it can sense what's also around me--a front and a back, as it were.
If I move in front of a Kinect, not only can it see what's in front and in back of me to sense the depth, but it also knows exactly how many IR lights it's shooting out across the room, the exact distance between each one--and which ones I am violating with my motions.
Surely it is easier to say, "He's blocking these lights, which means he's at point (x,y,z)," than it is to say, "If the table is 5 meters away and is 1.5 meters tall, but it looks like it is x meters tall from this distance, and the man here is approximately 2 meters tall, and he's shrinking and growing by this much--that means he's approximately this far from us and this far from the table...."
In pure logical terms, it seems like there would be a LOT of calculations need to be done if you were to want to use a 3D camera for the ENTIRE of the motion sensing--which would limit the amount of resources available to the rest of your program and...etc.
On a computer, this might not be a problem, given enough resources and given what you aim to achieve. On a console...I remember hearing that the Kinect did use the Xbox SPUs to run calculations and that that DID limit the overall system resources in some way. On a phone? I expect some problems.
Not only with how you might intend to use it, functionally (hold camera so other people could play games? Use it for AR purposes?), but with the resources available to do it with. These are all interesting ideas, but I'm not convinced that a phone is yet up to snuff to do such constant calculation and dynamic calibration on the fly.
But I've been known to be wrong.
...from time to time.
My thought was to eventually be able to run motion sensitive games directly form the Evo 3D in 3D. Put the phone in a central position above or below my tv, connect a compatible controller and play BAD ASS 3D games or semi cool 2D games.
... you know seeing my idea spelled out like this really shows me how farfetched it really is, oh well maybe in 5 years you never know.
The kinect also uses some proprietary technology that they own. Well they did once they bought the company who designed it.

I have the otterbox defender, and I've noticed when i open the camera and use it for 3D pictures, there seems to be a ghost of whatever I'm looking at, almost like the lenses are trying to create a side by side pic. Anyone else noticing anything like this?

No one?

You have to find the right viewing angle to see the 3D effect...I recommend viewing a 3D movie to get used to it first..cuz the 3D camera and the pics sometimes are shot in lower quality, therefore, 3D is not revealing as the movies.
I could see them just fine without the case, and still cancers my old ones fine, its just whatever new ones I take

Hmmmm, I've seen some ghosting, but I've always figured that it's normal. Depending upon the lighting, angle, and distance from object, the ghosting can be either very miniscule, or rather pronounced. As with any camera, it takes some experience to get down the right handling angles for the lenses given any particular situation. Keep playing around with the camera some, and then let us know how it goes. Try multiple shots from different angles with different settings for the same scene, and then see if you notice any differences.
FYI- I have the case you speak of, and sometimes I can see slight ghosting, others times I don't. If I take a really whacked out angle photo with bad lighting, from far too close a distance, then the ghosting is VERY pronounced. Also, the more complicated the image (ie, Taking a picture from inside a room, looking out through windows at a deck backed by trees, with sunlight streaming through), then the more likely some ghosting will be IME. However, in general outdoor daylight, with a simple object of focus (Like my dog laying down on the grass), I don't really notice it. Also, motion plays a role in it too.
do you see that when trying to take a vertical picture? thats the only time i have noticed a double image appearance.

[Q] 3D Photo & Video : Is my Evo 3D Faulty?

Hi guys!
Please Have a look attached file and advice me.
Is my evo 3d faulty? or common?
Need your help and opinion.
Thanks!

Never heard of this before .. according to your screenshot and your "good" and "bad" pictures, there appears to be an issue. where did you obtain the "good" picture from? do you have two evo 3d devices you're comparing side by side?
Suppose if you wanted to add measurements on the physical gap between the two cameras along with the screenshots, then others could also measure the gap between their cameras and post their results.
Measuring the gap seems to be a pretty quantitative method of analyzing the issue.
Keep us updated!

3d photos from other web site for your understand.
coz I'm not good at speaking english. ^^; so I made it
But I can say My 3d photos are always like wrong 3d style. it makes headach. T.T
And please googleing about 3d photography than you will know which is good 3d photo. ^^
Thanks.
That picture of your camera is not square. You need to center the camera over the red square

did you drop the phone at all. that looks like a probelm.
No I didn't..
Ignore a camera picture.
How is your photo look like?
you guys got 3d photo like a good 3d sample?
tell me and post your photo please.
I'd like to compare it.
Thanks.
Comparison
Ok, I think the position of both cameras are unimportant because. I think most of the corrections and overlaping of the images taken from the cameras and creating the 3d effect are software made (thats my opinion and my guess as an Electronic Engenieer). But I can't be sure because i wasn't in the design of the phone :S, jajaja... and I haven't even study about this process...
But I'll tell you what would I do for determining the problem.
The problem could be the display too... So i'd try taking a 3d pic and then look at it in other 3d device (maybe another evo 3d).
If the image is still the same, I'd try update firmware or Rom... or something in the phone software...
Think about the cameras, they are like eyes... and think about people, some have a larger space between the eyes than others and no one is perfect like your phone. It's the brain that fixes itself to watch the world in the better way.
If you have headache watching 3d pics, also you could be the problem jejeje... because you are not used to the watch it (like my father). Ask someone else if they have the same problem when watching 3d pics in your phone.
No no, that's not what I'm trying to say. ummm..
For example..If you want to take a 3d photo by 2 normal cameras. you must take a photo same level(horizontaly) of balance. because humen eyes like it.
if not same level of camera makes wrong 3D style of my smaple photo. Yes!! you can see this wrong 3d with 3d effect but it is not proepr method of take 3d photo. also gogleling LG3d camera photo sample. it is alligned verticaly.
I'm not good at speaking Eng. But I hope you guys understand what i'm talking to.
Thanks.
Maybe I don't understand what it takes to take a 3d pic.
Just think it's more like a software issue.
Also, the distance of the camera you are complaining about would result in a much more ugly photo because a little radious is higher at the distance.
When you are going to take a photo before you push the trigger, do you still see the it in a bad shape?
I also speak in Spanish, I'm from Mexico.
Feel free if it's easier in spanish but not in the forum, jejeje...
Please have a look this article.
Rotational and Vertical Disparities in Source Footage
Disparities corrected so all straight lines are parallel
Unwelcome Disparities (Geometric, lens and temporal)
Disparity is a “dirty word” for stereographers. In fact the only “good” type of disparity in S3D is horizontal disparity between the left and right eye images. As mentioned before, this is known as parallax.
Any other type of disparity in your image (vertical, rotational, zoom, keystone or temporal) will cause the viewers eyes to strain to accommodate. This can break the 3D effect and cause muscular pain in the viewer’s eyes or even nausea. Every stereographer will strive to avoid these disparities on set by carefully calibrating the steroescopic rig and it will be tweaked ever further in post production through the use of 3D mastering software.
From : http://www.dashwood3d.com/blog/beginners-guide-to-shooting-stereoscopic-3d/
So I think our camera has got Vertical Disparities problem. or my camera only?
If it is software problem. how can I adjust it? and finally don't you have this Vertical Disparities problem?
PS. You will not be able to 'see' this problem on your mobile screen, not until you put it on YouTube and can see what's going on when viewing anaglyph with no glasses on your pc. than You will notice it.
Thanks.
can you send me a pic taken from your phone?
I don't see any problems with mine.
